Abstract

A color changer has a valve block for connecting a plurality of coating material lines to an application device. The valve block has a parallelepiped housing. The housing has a central color channel with an axial direction and contains valve bores for receiving valves and a length of a central color channel is as short as possible with a simultaneous supply of many paint feed lines. A first number of parallel valve bores open into the color channel at first openings, a second number of parallel valve bores open into the color channel at second openings on the opposite side of the color channel and offset in the axial direction with respect to the first number of valve bores. A third number of parallel valve bores open into the color channel at third openings and a fourth number of parallel valve bores open into the color channel at fourth openings.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the priority, under 35 U.S.C. §119, of European application EP 10 009 212.1-2425, filed Sep. 6, 2010; the prior application is herewith incorporated by reference in its entirety.BACKGROUND OF THE INVENTIONField of the Invention

[0002] The invention relates to a color changer having at least one valve block for connecting a plurality of coating material lines to an application device. The valve block has a housing which is configured as a parallelepiped, and the housing has a central color channel with an axial direction and contains valve bores for receiving valves.

[0003] In modern coating assemblies, in particular in paint shops, the painting of objects, for example of bodies of motor vehicles, is carried out predominantly or even exclusively automatically and by machine. In processes of this type, paint is applied to the object to be painted with the aid of automatically controlled application devices. In many cases,...

Embodiment Construction

[0037]Identical parts are provided with the same designations in all the figures.

[0038]Referring now to the figures of the drawing in detail and first, particularly, to FIG. 1 thereof, there is shown a valve block 2 for a color changer having a cuboidal housing 8. A central color channel 20 runs between a front face 14 and a non-illustrated rear face which lies opposite the front face 14. A total of sixteen valve bores 26, 32, 38, 44 are let into the housing 8, into which valve bores 26, 32, 38, 44 pneumatically actuable valves can be inserted. Furthermore, sixteen feed line openings for the supply of paint are let into the housing 8. In each case one feed line opening 50 is assigned to in each case one valve bore 26, 32, 38, 44. In the operating state, the valves which are inserted into the valve bores 26, 32, 38, 44 open a connection between the feed line opening 50 and a central color channel 20 as required. After opening or producing a connection of this type or after producing ...
